The wedding video was lost and the wedding company defaulted. Both parties can solve it through consultation. The wedding company did not fully fulfill its obligations, which violated the rights of the bride and groom and should bear corresponding responsibilities. Responsibilities include service fee compensation and so on. In addition, according to Article 4 of the Interpretation of the Supreme People's Court on Several Issues Concerning Determining the Liability for Compensation for Spiritual Damage in Civil Torts: "If a specific commemorative item with symbolic personality is permanently lost or damaged due to infringement, and the owner of the item brings a lawsuit for compensation for mental damage to the people's court on the grounds of infringement, the people's court shall accept it according to law."
